I saw your post on GEN FORUM and I think we might have some Mericle's in common but just how I am not sure. There was also a gentleman that posted a message about MERICLE under that name on Gen Forum.
My husband's gg grandfather, James ROUSE was the son of unknown ROUSE and Sarah MERICLE (Supposedly) all from Ohio...Jefferson County area. They moved into Jackson County Illinois about 1847-48 as James was the youngest son and he was born in 1847 in OH. Sarah's Rouse husband died either before they left Ohio or right after they arrived there as she married a Pierson Duncan in 1849 In Jackson County .
A gentleman emailed me a short while back and said he thought for sure she was the daughter of Samuel Mericle of Jefferson County, Oh. I have not been able to prove this. It looks as if your family are the same people back in Ohio or somehow related.
It was told to me that Samuel was the son of Jesse Mericle that came from Bohemia to PA. as a Moravian missionary.
If any of this sounds familiar or if you think our families might be connected please let me know.
